Leptomorphus mandelai

Edited by cborkent on Sat, 01/05/2013 - 02:49
Etymology: 
This species is named in honour of former South African President Nelson R. Mandela, in recognition of his role in ending apartheid in South Africa and for his advocacy of peace, reconciliation and social justice.
Diagnosis: Based on: 
Systematics and Phylogeny of Leptomorphus Curtis (Diptera: Mycetophilidae)
Habitus: 
The only extant species of Leptomorphus with the following combination of characters: laterotergite, anepisternum and anepimeron yellow; scutellum yellow; scutum mostly dark brown with yellow restricted to anterior and lateral margins; abdomen with tergite 7 brown (Fig. 23); male genitalia with tergal evagination bearing ventrally-directed fold along most of posterior margin and small point on apicomedial corner (Fig. 109). This species can be distinguished from other Afrotropical species by the yellow scutellum, brown tergite 7 (Fig. 23), and lack of small setae covering the scutum (except along dorsocentral lines).

The generic name is based on the hemispherically humpbacked mesoscutum; hemisphaera (hemisphere) + notus (back). Gender masculine.
Head: Shape: 
Head moderately large, hemispherical, in dried specimens tightly attached to more or less concaved cervical and prothoracic regions under anterior 1/3 of mesoscutum, therefore head directed ventrally and morphological posterior margin of head almost dorsal. Frons 1.3 times as wide as long, more or less narrowed anteriorly; face twice as wide as long; clypeus as long as face, twice as long as wide; frons, face and clypeus without setae. Vertex short, greater part of vertex and occiput representing bottom surface of hemispherical head concealed in lateral aspect, short setose only on upper lateral areas of vertex.
Head: Ocelli: 
Ocelli 3 in number, arranged almost transversely, but middle ocellus slightly shifted anteriorly from lateral pair, middle ocellus half as large as lateral pair in diameter, lateral pair situated midway between middle ocellus and inner eye margin.
Head: Eyes: 
Compound eyes oval, with inner margin almost straight, not emarginated above antennal bases, densely covered with inter-mmatidial setae 3 times as long as diameter of ommatidium; vertical diameter of eye 1.4 times as long as transverse diameter.
Head: Antennae: 
Antenna moderately long for Grioristini, longer in male than in female; scape as long as thick and short setose, pedicel spherical , half as long as scape, and short setose on ventral surface; flagellum consisting of 14 flagellomeres , each flagellomere pale pilose and bearing several short black setulae more abundant on basal flagellomeres; 1st flagellomere several times as long as thick; distal flagellomere almost as long as penultimate.
Head: Mouthparts: 
Mouthparts short; labrum triangular, almost as long as face; labella small , very short setose; maxillary palpus greatly shortened, 2/3 as long as height of compound eye, 1st and 2nd palpomeres united into short segment with some setulae, 3rd spherical and with large sensory area occupying most of mesal surface and bearing some 10 setulae, 4th cylindrical , as long as 3rd , 5th longer than 4th and with several setulae towards tip
